AEM Site Theme Builder

This repository contains scripts for building a Site Theme, ensuring compatibility with the requirements of AEM Site Templates. The recommended way of integrating the Theme Builder is to install it as an npm dependency of the Site Template Theme. This way aem-site-theme-builder commands can be used in NPM scripts. Example of such integration can be found in Standard Site Template.

Installation

cd <your-site-theme>
npm install @adobe/aem-site-theme-builder --save-dev

Usage

Proxy

Proxy your site running on AEM as a Cloud Service to localhost and replace requests made to the Site Theme with your locally compiled version of the Site Theme.

npx aem-site-theme-builder proxy

The URLs to a Site Theme can be provided via .env described in environment variables. In order to inject your locally compiled theme, the location of compiled site theme must match.

Live Preview

The live preview will run proxy server (desribed above) as well browser sync functionality. Browser sync will point to the proxied page and will be looking for changes in the dist folder and will refresh the page each time you got a change.

npx aem-site-theme-builder live

Theme Deployment

1. Compile your theme and make the artifact available on GitHub. AEM as a Cloud Service will try to access https://api.github.com/repos/%GIT_ORG%/%GIT_REPO%/actions/artifacts/%GIT_ARTIFACT_ID%/zip in order to download the theme.
2. Execute npx aem-site-theme-builder deploy in order to update the reference on AEM as a Cloud Service.

Complete development workflow

In order to make best use of theme-builder you have to run the live preview which provides proxy and browser sync functionalities. On top of that you need to make sure that you have additional watcher for your source files that triggers your theme build process which produces changes in the dist folder of your theme. This way after making change in your source file you will get your proxy page refreshed via browser sync.

API

Environment Variables

Theme Builder scripts are based on the environment variables you provide. These variables are used to properly provide live preview and deploy functionality of the AEM Site Theme Builder.

Here is the list of required variables:

AEM_URL=<URL of the AEM as a Cloud Service instance>
AEM_SITE=<name of the AEM site>
AEM_PROXY_PORT=<localhost proxy server port>

Here is the list of optional variables:

Recommended way to define site variables is to use / create .env file within your theme project repository.
